Spurs won't sign Leonard by deadline

There is a strong likelihood that Friday's midnight deadline for contract extensions for first-round picks from the Class of 2011 will pass without a new deal for reigning NBA Finals MVP Kawhi Leonard, according to league sources.

Sources told ESPN.com this week that Leonard and the San Antonio Spurs, despite more serious discussions between the parties in advance of the Halloween buzzer, are unlikely to come to terms during this extension window, setting up the 23-year-old to become a restricted free agent in July.
